swh/clearlydefined/mapping_utils.py
158

source.get("url") may return None, so for that I have used this line, and url should be str, not Optional[str] that will be returned by source.get("url") to prevent mypy error here

161

Same reason for sourc.get("url")

191

The case in test_map_row_with_invalid_ID_without_revision

193

The case in test_map_row_with_invalid_ID_without_json_extension

212–213

The case in test_map_row_with_empty_metadata_string, I have seen in clearcode toolkit DB, some rows might not have metadata at time of scan, it may gradually fetch that data after a while.

swh/clearlydefined/mapping_utils.py
158

If the URL is expected to always be either None or a string, then test if it is None, and if it's not, assert it's a string.

That way we get an error at runtime instead of silently ignoring the unexpected data type.

191

Could you explain this in a comment (as well as the ones below)?

swh/clearlydefined/mapping_utils.py
158

Got it

191

Sure

@vlorentz made the suggested changes, thanks for a detailed review :)

some of your test code doesn't run, see the coverage mark on the right.

And instead of testing the error message (which is brittle), you should raise different exception types.

And it's still missing tests for when the returned flag is expected to be True

swh/clearlydefined/mapping_utils.py
143

when does this happen in practice?

183–184

when does this happen in practice?

213–216
241–242

shouldn't this be an error?

swh/clearlydefined/tests/test_mapping_utils.py
131 ↗(On Diff #17744)

can you refine the return type?

This revision now requires changes to proceed.Jan 29 2021, 2:55 PM
swh/clearlydefined/mapping_utils.py
143

Yes, you are right, this line won't get hit in practice

183–184

Yes you are right, it won't happen in pratcice

241–242

IMO more tools can be used by clearcode toolkit in future and in that case we should save them for future mapping.

swh/clearlydefined/tests/test_mapping_utils.py
131 ↗(On Diff #17744)

Sure

swh/clearlydefined/mapping_utils.py
241–242

then we should either raise an error here so we don't ignore them silenty, and be generic enough to support new tools.

TG1999 added inline comments.
swh/clearlydefined/mapping_utils.py
241–242

Sure

TG1999 added inline comments.
swh/clearlydefined/mapping_utils.py
183–184

Actually this line got hit, when metadata is wrongly formed, should I raise an error for it ??

swh/clearlydefined/mapping_utils.py
183–184

depends when/why it's triggered. If you know for sure that will happen, then you need to handle it because we don't want the script to crash in production.

You missed this comment:

Could you also document better your map_* functions? ie. the return type should be more specific than list, and you should explain what that list contains.

And they are all very similar, especially the content of the for loop. As all three are only called from map_harvest, this work could be done in map_harvest. I'm not completely sure, but making them generator functions might help


And for this:

You're parsing/validating list_cd_path in two different places. This increases the risk of bugs and mismatches between the two codes.

Just parse it once and for all in a single place.

you moved the code around, but you're still validating twice in the same function.

swh/clearlydefined/error.py
1 ↗(On Diff #17768)

only 2021

6 ↗(On Diff #17768)

Better name, please.

7–11 ↗(On Diff #17768)

this is not needed, the base exception handles it properly already.

14–35 ↗(On Diff #17768)

Could you add docstrings explaining the meaning of each of these?

swh/clearlydefined/mapping_utils.py
1

(also 2021 or 2020-2021 while we're at it)

21

the argument name should only be "storage", for consistency with the rest of the codebase. And we prefer it to be the first argument (same reason)

63

please rename this. "flag" is synonymous with "boolean", which doesn't convey the meaning of this variable.

(same comment below)

swh/clearlydefined/tests/test_mapping_utils.py
245 ↗(On Diff #17768)

same comment on "flag"

This revision now requires changes to proceed.Feb 1 2021, 12:15 PM

and there's again some unreachable code in the tests; please check this before submitting diffs.

And there are two lines in the with pytest.raises blocks; only the line expected to raise the exception should be in the block.

ok I'm accepting this diff, but let's try to to deduplicate these functions after it's merged.

Add mapping for definitions and harvests
Use swh storage instead of sql queries to map sha1 with SWHIDs
Add different type of error classes in error.py
Add function map_row, and try to check if the ID of the row is valid ID or not, if it is not a valid ID, then raise different exceptions defined in error.py. And if the ID is valid then check if the ID is a definition or harvest.
If the given ID is a definition then map the hashes with the archive (sha1 with content and sha1git with revision) and return a valid SWHID, TargetType(revision/content), Origin
If the given ID is a harvest, then check the tool of the harvest (licensee, scancode, clearlydefined) and map accordig to the tool (map_licensee, map_scancode, map_clearlydefined), then return mapping status of that harvest (True if every sha1 of that harvest is mapped and False if failed to do it) and a list of data([SWHID,TargetType,None]).
Add tests to cover all the cases"

Add feature to map a row from clearcode toolkit database with content and revision table from software heritage archive
This is to build a mechanism to map a row [path(Primary Key), content(binary data), last_modified_date(timestamp with timezone), map_error(error message while mapping), uuid] from clearcode toolkit database, with software heritage archive using content table for sha1 and revision table for sha1_git and extract required information from that row. Then return list of data that has been mapped and mapping status(if able to map every hash of that row, will return True, else return False) so the row that is not being able to map for now can be stored in a state, and can be mapped in future.
Add various exception classes in error.py that can be raised while mapping a row. Check if that row is a definition or harvest and also check if that row does not has invalid path, raise exception if path is invalid. If row is a definiton then map the data using map_definition and if it is a harvest then map it using map_harvest. Use storage instead of sql queries while mapping with the data inside archive. Add tests to cover all the cases and add docstrings to explain how every function works.
